Editor's note

If you’ve recently had your blood pressure checked, you might know that doctors start getting concerned if your systolic (that’s the top number) reading is around the 140mmHg mark. That has long been the diagnostic cut off for hypertension, or high blood pressure, which is one of the risk factors for heart disease and stroke.

But two US bodies recently recommended lowering the diagnostic threshold to 130mmHg. If this becomes standard practice, millions of Australians will suddenly be labelled “hypertensive”. Katy Bell and colleagues write that this will only benefit a minority of these people – while most may just end up anxious and overmedicated.

Previously, a person would be diagnosed with high blood pressure if their systolic reading was 140mmHg. But it's recommended this threshold be lowered to 130mmHg, which will do more harm than good.
